Naiad, Thalass, Galatea, Larisaa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, and Neso.
Neptune has 14 known moons. Their names, in order of distance from the planet, are Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, Neso, and Hippocamp.
Halimede, the ninth moon of Neptune, orbits at an average distance of about 15.7 million miles (25.3 million kilometers) from the planet.
The moon is about 384,403 kilometers (238,857 miles) from Earth, and about 4,564 million kilometers (2,835 million miles) from Neptune. So, the moon is much closer to the Earth, Neptune over 10,000 times farther away.
First of all why do you say YOUR solar system?? The planet is neptune and it has 13 moons which are: Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, and Neso.
Neptune's moons are Galatea, Despina, Thalassa, Naiad, Larissa, Proteus, Triton, and Nereid. Only Triton and Nereid are large enough to be seen by Earth-based telescopes.
The first four moons of Neptune, Naiad, Thalassa, Despina, and Galatea, are so close to Neptune that they orbit within its ring system. Little is known about them. The next one out, Larissa, was actually discovered in 1981, when it blocked a star. This was attributed to the ring arcs, but later was found to be the moon, being re-discovered by Voyager 2 in 1989. Proteus is the second-largest moon in orbit around Neptune. It is so close to the planet that Earth-bound telescopes cannot see it.
By Triton I presume you mean our Neptune's biggest moon Neptune is little over 450 Billion miles from the sun and that would be 720,000,000 kilometers from the Sun or a little more Neptune's Biggest Moon Triton (2540 ks across) is one of the coldest objects ever resourced in our solar system Triton is smaller than our moon but further from its planet Neptune than our moon is from Earth, Triton is 354,000 kilometers in orbit around Neptune All in all this means that Triton is approximately 720,000,000 or 720 billion kilometers from the sun
Neptune's 13 moons are Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, and Neso.
